BURNER.

To all whom it may concern:

Be it known that I, AnoLr P. LINK, citizen of the United States of America, residing at Brooklyn, New York, have invented certain new and useful Improvements in Burners, of which the following is a specification.

My invention relates generally to hydrocarbon burners, and has especial reference to heaters adapted for burning oils of practically any specific gravity.

One object of the invention is to provide a simple form of burner which be cheaply constructed to economically and noiselessly burn oils, greatly varying in specific gravity, with an intensely hot flame.

A further object is to provide effective means, in a burner of this character, for preventing carbonization of the fuel on the walls of the container therefor.

A further objectis toavoid the necessity of providing means extraneous to the burner to furnish an adequate air supply or. draft, and to so construct the burner that it will be self contained and embody in its structure means which may be increased or decreased as desired for supplying as abundant an air supply as if an external forced draft were present.

A further object of the invention is to this type for containing a liquid which performs the triple function of preventing carbonization of the fuel on the walls of the fuel container, assisting in vaporizing or comminuting the fuel, and in creating a draft to furnish an adequate supply of air to form the combustible mixture.

A further object is to provide simple means for feeding fuel and liquid to, and draining the same from, the burner.

A still further object of the invention is to provide means in the air tubes or passages for preventing the drip on to the ground or floor of any oil which may overflow from the oil container or escape through the jet tubes of the burner.

Other objects and advantages of the invention, and its structure and operation will be clearly disclosed in the following description, reference being had to the accompanying drawing, wherein' Figure 1 is a substantially central vertical sectional view of a burner embodying my invention; Fig. 2 is a horizontal sectional of Fig. 1; Fig. 3 is a Specification of Letters Patent.

In one practical embodiment of the invention I employ a suitably formed casing openatthe top and comprising the base 10 and lateral wall 11. The casing may be made in any desired shape, but I have found a cylindrical casing to be best adapted for the purpose and have soillustrated it in the drawing. Projecting through the base 10 into the interior of the casing is a preferably frusto-conical central air tube or I duct 12 the smaller end of which opens into the casing substantially at a point in line I with the median part of the wall 11. At {its lower end this duct is preferably in- I wardly curved or turned, as at 12*, for a purpose to be later explained. Arranged I concentrically about the central tube 12 is a substantially annular air conduit 13, of (frusto-conical formation, the lower walls of the conduit 13 being flared and at their inner surfaces contacting with the lower outer surfaces of the central tube. By this arrangement the least possible obstruction to the admission of air is presented. The

lower edges of the are inturned at 13 Arranged substantially in line with the top of the air tube 12 and the conduit 13 is a series of orifices 14 formed in the casing wall 11, these orifices being preferably of angular elongated formation to present as great an area as possible for admission of atmospheric air to the interior of the burner at this point.

The hydrocarbon (oil) containing means may be of any suitable construction, and for my purpose I have found the form clearly I shown in Fig. 1 to be most effective. This l form of oil container includes a tray or receptacle 15, provided with a depression 16 I which serves as the oil container proper. The lateral wall of each oil container is preferably slightly inclined so as to make the container somewhat conical. and the container itself is annular in form, sur- 'rounding and snugly resting against the exterior surfaces-of the air tube 12 and the walls .of'the conduit 13 v provide the bolts 17 passing through the container base and the casing base, and the winged nuts 18 for engaging the threaded ends of the bolts. Extending from the walls 16 of the oil containers is a series of jet tubes or nozzles 19 inclined in the direction of the containers 1(5 and openings 14 the mouths or emission openings of said nozzles being substantially elliptical in shape. The base of the containers 16is spaced away from the base 10 of the casing so as to form a chamber 20 to receive water or any other readily vaporizable liquid 21.

I preferably provide inner and outer concentric trays or oil containers 15, each having an oil containing depression 16. The depression in the inner tray is provided with oil in any suitable manner, as by pouring the oil into the depression, while the outer oil containing depression 16 has an orifice 22 in its vertical wall which is in communication with the-open. end of a pipe 22 leading to a source of oil supply (not shown). The pipe 22 is provided with a gage 23 to show the level of oil in the outer container 16, and also has a cock 24: for governing the flow of oil into and out of the said outer container 16. The chamber 20 in the casing 10 is in communication with a suitable source of water supply (not shown) by means of the pipe 25, provided with the gage 26, and having the siphon 27 and the valve 28, the latter operating substantially in the same manner as the valve 24; in the oil pipe 22.

The air tube 12 and conduit 13 are internally ribbed, the ribs 29 being, inwardly projecting to impede the downward passage of any oil which may overflow from the burner.

Suitably supportel over the' upper openings inthe central air tube and the concentric c'onduit are hoods or deflectors 30 which are both centrally and laterally curved so as to deflect air entering through the tube 12 and the conduit 13 to both sides of the hoods and over the fuel in the containers 16.

The modified form of the invention shown in Fig. 3 differs from the preferred form in having a baflie wall 31 of fire brick or the like so arranged above the burner that, if the rising vapor is charged with liquid or non-vaporized particles, the heat of the wall 31 will tend to vaporize such particles.- The wall 31 is provided with the transverse openings 32 and is secured to the burner at its upper edge, as shown.

My invention is applicable to numerous uses, but it is especially designed for, and has been found to be thoroughly efficient as, a heat-er for boilers employed for domestic purposes. Assuming the heater to be constituted as shown in the drawing and to be installed under the ordinary domestic Water boiler the operation is as follows :Water is permitted to flow into the space 20, and thereafter oil in suitable quantities is permitted to flow into the containers 16, and the oil is ignited by a piece of burning waste or the like causing the water to boil. The heat of the boiling water transmitted through the lateral walls of the container 16 will cause vapor to arise from the oil, and this vapor, which mixes with steam coming through the jets'19 and air issuing through the tube 12 the conduit 13 and the openings 14 forms a highly combustible mixture which, when once ignited by a flame within the burner, sustains combustion as long as oil is fed to the oil containers. The baflie plates 30 will direct the air coming through the tube 12 and the conduit 13 over the oil containers, the openings 1 1 will also directthe air over the containers, and the jets 19 will have a like effect on the steam, these several instrunientalities acting in the nature of a Bunsen burner, directing toward each other steam and air which mixes with hydrocarbon vapor, formii'ig two streams which then spread out and burn with an intensely hot flame. The forcible issuance of the steam through the jets tends to create a vacuum in the burner whereby air will be forcibly sucked in through the tube 12, conduit 13 and openings 1a, which action will be in the nature of a forcedv draft, thus providing for an abundant supply of air, under all conditions, to the mixture. Should there be any oil overflow either from the containers or by vapor condensation, and the overflow pass down through the tube- 12 and conduit 13 the ribs 29 will retard the flow and as the tubes are fairly hot any such overflow will vaporize before it reaches the lower end of the tubes and. conduit. If, however, all the overfiow should not so vaporize the inturned edges of the tube and conduit will act as a drip pan and prevent the oil from falling to the floor. If particularly heavy oils are to be used, I employ the modifled form of Fig. 3, the baffle wall. 31- acting as a heat vaporizer for any liquid particles carried-upward by the vapor. When. the action of the heater is to bestopped the oil supply is shut 05 and. the cook. 24 opened to drain the oil out of the containers 16. Thereafter the water, may, if desired, be drained out of the space 201 Owing to the presence of the boiling water in contact with the oil containers 16, all the oil will be vaporized and no carbo-nization. on the inner walls of these containers will, take place.

Despite the strong draft in the burner, due in part to the action of the steam, I have found that in operation the burner is practically noiseless which is a great desideratum and the accomplishment of which has been attempted, but unsuccessfully I believe, in numerous instances. It will also; be understood that the tray or receptacle is removable as a whole, so that ready access may be ing and other purposes.
